Common JSON to YAML Use Cases
- Converting Kubernetes resources from JSON to YAML for version control
- Creating Helm chart values files from JSON configuration
- Migrating JSON config files to YAML for better readability
- Preparing Ansible playbook variables from JSON data
- Converting CI/CD pipeline definitions to YAML format
- Transforming API responses into YAML configuration files
All conversion happens entirely in your browser. Sensitive configuration data, credentials, and infrastructure specifications are never transmitted to any server.
Examples
Example 1: Simple Configuration Object
Input JSON:
{
"app": {
"name": "my-service",
"port": 8080,
"debug": false,
"allowed_origins": ["https://example.com", "https://app.example.com"]
}
}Output YAML:
app:
name: my-service
port: 8080
debug: false
allowed_origins:
- https://example.com
- https://app.example.com
The YAML output is more compact and readable than the JSON source. No curly braces, no quotes around keys, and arrays use the clean dash-item syntax.
Example 2: Kubernetes Deployment Manifest
Convert a Kubernetes deployment from JSON (returned by kubectl get deployment -o json) to YAML for version control:
Input JSON:
{
"apiVersion": "apps/v1",
"kind": "Deployment",
"metadata": {
"name": "web-app",
"namespace": "production",
"labels": { "app": "web-app", "tier": "frontend" }
},
"spec": {
"replicas": 3,
"template": {
"spec": {
"containers": [
{
"name": "web",
"image": "nginx:1.25",
"ports": [{ "containerPort": 80 }],
"resources": {
"requests": { "cpu": "100m", "memory": "128Mi" },
"limits": { "cpu": "500m", "memory": "512Mi" }
}
}
]
}
}
}
}Output YAML:
apiVersion: apps/v1
kind: Deployment
metadata:
name: web-app
namespace: production
labels:
app: web-app
tier: frontend
spec:
replicas: 3
template:
spec:
containers:
- name: web
image: nginx:1.25
ports:
- containerPort: 80
resources:
requests:
cpu: 100m
memory: 128Mi
limits:
cpu: 500m
memory: 512Mi
Example 3: Helm Values File
Convert JSON values to YAML for a Helm chart values.yaml file:
Input JSON:
{
"replicaCount": 2,
"image": { "repository": "myapp", "tag": "1.2.0", "pullPolicy": "IfNotPresent" },
"service": { "type": "ClusterIP", "port": 80 },
"ingress": { "enabled": true, "host": "myapp.example.com" },
"resources": { "limits": { "cpu": "200m", "memory": "256Mi" } }
}Output YAML:
replicaCount: 2
image:
repository: myapp
tag: 1.2.0
pullPolicy: IfNotPresent
service:
type: ClusterIP
port: 80
ingress:
enabled: true
host: myapp.example.com
resources:
limits:
cpu: 200m
memory: 256Mi
